United Electric (UE) One Series Hybrid Pressure and Temperature Transmitter-Switches

The latest release of United Electric's One Series provides explosion-, flame-proof, intrinsically safe, and non-incendive devices to monitor gauge pressure, differential pressure, or temperature for critical alarm and shutdown applications in harsh, hazardous environments. With a digital process display and available 4-20 mA output, the One Series can provide the functions of a switch, a gauge, and a transmitter with only one connection to the process.

UE One Series is available in two-wire analog loop powered, two-wire discrete input powered, and externally powered models, and as switch-only, transmitter-only, or transmitter/switch versions. Transmitter and hybrid transmitter-switch One Series now feature HART® communications so you can program or troubleshoot without removing the enclosure cover to maintain device integrity, even in explosive environments.

Key Specifications

  • Switch only, transmitter only, or hybrid transmitter/switch models available
  • Two new switch-only models now available: High voltage, low current for compatibility to worldwide DCS and PLC systems, and high voltage, hig current for switching high level loads directly at the measurement point
  • NAMUR standard and HART® enabled transmitter; 4-20 mA output plus programmable switch for process monitoring, alarm, and shutdown
  • Switch-only models replace mechanical switches for cost-effective upgrades using existing wiring
  • Adjustable Ranges: Pressure -14.7 to 6000 PSI, Temperature -40° to 1000°F, Differential Pressure 0 to 200 PSID
  • Configurable "I Am Working" self-diagnostics ensure the instrument is fuctioning properly
  • Display and keypad provide easy, fast, secure field programming without taking the device out of service
  • Programmable setpoint and deadband provide versatile, accurate, repeatable alarm and shutdown switching
  • All models UL, CSA approved for Class I Div 1, Class II Div 1, Class III, plus Class 2 Zone 1, and Class 1 Zone 2 environments
  • Need a transmitter/switch for functional safety applications?
